1,Ukugcinwa kwecala lonikezelo kuqhuba ukukhula kwemarike yokuhlola

Phakathi ukuya ekupheleni kuka-Matshi, kunye nokukhutshwa kweendaba zokugcinwa kwezixhobo ezininzi ze-PC ezifana ne-Hainan Huasheng, i-Shengtong Juyuan, kunye ne-Dafeng Jiangning, kukho iimpawu ezintle kwicala lokubonelela kwimarike. Lo mkhwa uqhube ukunyuka okuthe tye kwimarike yendawo, kunye nabavelisi bePC benyusa iikowuti zabo zasefektri nge-200-300 yuan/toni. Nangona kunjalo, njengoko singena ku-Epreli, iziphumo ezilungileyo zexesha elidlulileyo ziye zabuthathaka ngokuthe ngcembe, kwaye amaxabiso amabala awazange aqhubeke nokunyuka, okukhokelela ekunyukeni kwesithuba kwimarike. Ukongeza, ngamaxabiso aphantsi ezinto ezikrwada, amanye amaxabiso ebhrendi ade ehlile, kwaye abathathi-nxaxheba bezentengiso bamkela isimo sengqondo sokulinda kwaye babone malunga nemarike yexesha elizayo.

2,Ukusebenza kwexabiso eliphantsi le-bisphenol A ekrwada inenkxaso encinci yeendleko zePC

Ixabiso le-bisphenol A eluhlaza lihlala liphantsi kutshanje, nangona inkxaso eqinile evela kwi-benzene ecocekileyo, ukusebenza kokubini ukubonelela kunye nemfuno akukwanelisi. Ngokubhekiselele kunikezelo, ezinye iiyunithi ze-bisphenol A ziya kulondolozwa okanye zicuthwe umthwalo ngo-Epreli, kwaye kukho izicwangciso zokwandisa umthamo wemveliso, onokunyusa imveliso. Ngokwemfuno, ngenxa yokugcinwa kakubi kwezixhobo zePC nganye kunye nemfuno yeetheminali ze-epoxy resin, imfuno esezantsi yomlambo yamacandelo amabini aphambili e-bisphenol A iyancipha. Ngaphantsi komdlalo wokubonelela kunye nemfuno kunye neendleko, kulindeleke ukuba ixabiso le-bisphenol A liya kubonisa ukuguquguquka kwekhefu kwinqanaba elilandelayo, kunye nenkxaso yeendleko ezincinci zePC.

3,Ukusebenza kwezixhobo zePC kuzinzisa, kwaye izibonelelo zokugcinwa ziyancipha ngokuthe ngcembe

Ukusuka kutshintsho lwamva nje lwezixhobo zePC eTshayina, uninzi lwabavelisi babonise ukusebenza okuzinzileyo kwezixhobo zabo. Njengoko i-Hainan Huasheng ingena kwixesha lokugcinwa, izinga lokusetyenziswa kwekhono lokuvelisa i-PC liye lancipha, kunye nenyanga ngenyanga yokuncipha kwe-3.83%, kodwa ukunyuka konyaka-ngonyaka kwe-10.85%. Ukongeza, isixhobo se-PC ye-Shengtong Juyuan sikwacwangciselwe ukugcinwa ekupheleni kuka-Epreli. Nangona kunjalo, iziphumo ezilungileyo eziziswa ngolu hlolo zikhutshwe kwangaphambili, kwaye impembelelo yabo kwimarike iyancipha ngokuthe ngcembe. Ngeli xesha, kukho amahemuhemu kwintengiso yokuba iHengli Petrochemical's PC plant iya kuqaliswa ukusebenza ekupheleni kwenyanga. Ukuba iindaba ziyinyani, zinokuzisa ukomelela kwimarike yePC.

Uphuhliso lwakutsha nje kwizixhobo zePC zasekhaya

4,Ukukhula okucothayo kusetyenziso olubonakalayo lwePC kunye nenkxaso yemfuno elinganiselweyo

Ngokweenkcukacha-manani ukusuka ngoJanuwari ukuya kuMatshi, izinga lokusetyenziswa kwamandla kwishishini lePC yasekhaya liye laphucuka ngakumbi, kunye nokunyuka okuphawulekayo konyaka kwimveliso. Nangona kunjalo, kubekho ukuhla okubonakalayo kokungeniswa kwamanye amazwe, okubangele ukukhula okuncinci kusetyenziso olubonakalayo. Imeko yenzuzo yoshishino lwePC yasekhaya iphuculwe kakhulu kwikota yokuqala, kunye nabavelisi benyusa imveliso kunye nezixhobo ezisebenza kakuhle. Nangona kunjalo, nangona ukusetyenziswa komjelo osezantsi kunolindelo oluthile oluqinisekileyo, imfuno eqinile yeePC kunzima ukuba yinkxaso eyomeleleyo yokuqhuba imarike.

5,Imakethi yePC yexesha elifutshane inokujolisa ikakhulu ekudibaniseni nasekusebenzeni kwangethuba lokunyuka kwamaxabiso

Ngokusekwe kolu hlalutyo lungentla, kusekho inkxaso yecala lokubonelela kwimarike yangoku yePC, kodwa uxinzelelo kwiindleko kunye nemfuno ayinakuhoywa. Ixabiso eliphantsi le-bisphenol A ye-raw material inenkxaso encinci yeendleko zePC; Nangona kunjalo, ukukhula kosetyenziso olusezantsi kuyacotha, okwenza kube nzima ukubonelela ngenkxaso emandla yemfuno. Ke ngoko, kulindeleke ukuba kwixeshana elifutshane, imakethi yePC inokugxila ikakhulu ekudityanisweni kwemarike yesithuba kunye nokusebenza.
